[Windump] syntax error about -w

[赵@博路电信idc]

windump  hi 

i want the windump to write the raw packets to file rather than parsing and printing them out 
then i typed this in the cmd:

 WinDump.exe host 61.142.15.58 -w d:\log

and then i got the following error messages:

E:\>WinDump.exe host 61.142.15.58 -w d:\log
WinDump.exe: listening on \Device\NPF_GenericDialupAdapter
WinDump.exe: syntax error

if i just type :   WinDump.exe host 61.142.15.58 
it worked well

i do not why it did not work well  using the option  -w
Any advises are appreciated

Thank you 
Best RGDS!
